A bunch of new cards were revealed in the first game of the final reveal stream.

Kobolds and Catacombs, Hearthstone's next expansion, releases this Thursday (Dec. 7) in the Americas region. It will then launch in Europe and other regions on Dec. 8. That means there's still time to pre-order a 50 card bundle, which comes with an exclusive card back.

Dark Pact is the final common minion for Warlock in this set. It's a one mana spell that destroys a friendly minion in exchange for restoring eight health to your hero. With tons of Deathrattle options, particularly in the new set, this could help Control Warlock.

Hunter is getting lots of wolves in this set, and this is another spell card that summons them. Hunter is going to get a lot of spells in this set, as Spell Hunter appears to be Blizzard's focus.

Of course the Hunter legendary was also shown off—and Day9 missed lethal to play it. We saw just how unreliable it can be though, as a lot of Hunter spells are not good.

The set includes 135 new cards, including two legendaries for each of the game's nine classes—a legendary minion and a legendary weapon.

Kobolds and Catacombs is the final set of the 2017/18 standard set calendar, the Year of the Mammoth. When the next expansion arrives in the Spring, the game's three oldest expansions will rotate out.
